Termite Damage in Your Crawl Space

Termites are often a problem in New Haven crawl spaces, with the most common species being Reticulitermes flavipes — or the Eastern subterranean termite. When these creatures enter this area, they can cause serious damage that puts your home’s foundation at risk.
Dealing with the fallout from a termite infestation in your crawl space is no joke. However, working with a repair expert like Groundworks can restore the structural stability of your home, protecting you and your loved ones.
What Is Crawl Space Termite Damage?
Despite normally thriving in warm climates, termites pose a huge risk in Connecticut, mainly because they can go undetected in damp environments like basements and crawl spaces for many years.
Several types of termites are known to inflict damage on homes in our state, but the most common is the Eastern subterranean termite. Like all termites, it feeds on crawl space materials like wood and, in worst-case scenarios, can cause ceilings and floors to collapse.
Signs of Crawl Space Termite Damage
You may have a termite problem in your crawl space if you notice any of these issues:
- Damaged floor joists and structural beams
- Holes in wooden surfaces accompanied by a material that looks like sawdust (this is the substance excreted by termites)
- Weakened wooden framing around a crawl space door or window
Termites are often attracted to moisture, so also look out for any of these signs in your crawl space:
- Water accumulation or flooding
- Wet insulation
- High humidity
- Mold growth
- Higher-than-usual electric bills
The floors in your home might also sag if you have excess moisture in your crawl space.
Moisture problems are common in many New Haven homes because of heavy rainfall and our proximity to various rivers, including the West, Mill, and Quinnipiac.
Inspecting your crawl space for termites can be dangerous, especially if you’re not wearing protective clothing. That’s because this area may contain exposed wiring that leads to electric shocks. Contact a professional like Groundworks to examine your crawl space instead.
How To Fix Termite Damage in Your Crawl Space
The first thing to do if you have termites in your home is to contact a professional pest control expert. They can lay down baits and treat the soil around your property with a termite insecticide, preventing these creatures from causing further damage.
Once your termite problem is under control, it’s time to call in the experts at Groundworks. Serving New Haven and the surrounding areas, we can inspect your crawl space and recommend repair solutions that safeguard your home, including:
Fixing Damaged Floor Joists and Other Components

Termites often eat away at crawl space subfloors and damage adjacent floor joists, which can destabilize a crawl space foundation. If this is the case, you might experience bouncy, sagging, or uneven floors.
Our team can replace damaged floor joists and use heavy-duty crawl space jacks to support them and potentially restore floors to their original level. Our crawl space jacks also provide support for structural beams and other components.
Waterproofing Your Crawl Space
Because excess water can attract termites, we recommend waterproofing your crawl space to prevent their return. Our waterproofing solutions include:
- Vapor barriers that help control water vapor in this part of your home
- Sump pump systems that collect water around your foundation and divert it to an external drainage system, preventing it from entering your crawl space
- Dehumidifiers that reduce the amount of crawl space moisture by maintaining optimal humidity levels

FAQs
Absolutely. Termites can cause significant structural damage, particularly if an infestation is left untreated for a long period. They can weaken wooden structures, leading to costly repairs.
Termites are attracted to moisture, wood, and warm, dark places. Leaky pipes, wet insulation, poor drainage, and damp basements can make your home more susceptible. They also feed on wood, paper, and other cellulose-based products.
Look for signs like wood damage, mud tubes on exterior walls, discarded wings near doors or windows, and hollow-sounding wood. Termite droppings, resembling sawdust or coffee grounds, can also indicate an infestation.
